grant

Although, the length of utility and plant patent protection (patent term) was previously seventeen years from the date of patent grant, utility and plant patents filed after June 8, 1995 now have a patent term of up to twenty years from the date of filing of the earliest related patent application. Utility and plant patents which were applied for prior to June 8, 1995, and which were or will be in force after June 8, 1995, now have a patent term of seventeen years from the date of patent grant or twenty years from the date of filing of the earliest related patent application, whichever is longer. Utility patents are subject to the payment of periodic maintenance fees to keep the patent in force. Patent terms can be extended under some specific circumstances. See the U.S. Code Title 35 - Patents for a full description of patent laws.

In Article I, Section 8 of the Constitution of the United States it says, " Congress shall have power [...] to promote the progress of science and useful arts by securing for limited times to inventors the exclusive right to their respective discoveries."

In your written patent application you must fully describe your invention to such a degree that a person skilled in the same field as the invention could make or use that invention. A person skilled in the same field as the invention should be able to read your patent application and understand it. The inventor must be able to make claims about his/her invention in clear and definite terms.The part of a patent application that describes and reveals your invention is called the specification and includes various types of descriptions, claims, and drawings depending on the type of invention and type of patent involved. Remember, ideas alone cannot be patented. In other words - you can't just write, "I have an idea for a new alarm clock." You must be able to describe how your alarm works so that an expert in alarm clocks would understand how it would work and that it would indeed work. It's like a recipe ... a good cook should be able to produce your invention based on your patent. As a novice, to file your first patent application yourself is often unwise. However, you could write your own descriptions and then pass them over to your attorney. The attorney could use your writings as a guide and a time-saver, and that will save you money. You should present your inventor's logbook, prototype, and any prior art searches to the attorney. You must write a complete and thorough description of your intellectual property as you cannot add any new information to your patent application once it is filed. You can only make changes to the subject matter that could be reasonably inferred from the original drawings or description.
